To all whqm, it may eminem:

Be it known 'that I, OARL JoHAN BIBoW JENsnN, a subject of the King 'of Denmark, iresiding at the city of Horsens, in the Kingv5 dom of Denmark, have invented certain new and useful Improvements in Parquetry, of

which the following is a specification.

My invention relates to parquetry and it consists in a new manner to compose parquetry v by means of small pieces of Wood and lists ingwill never have any influence on the par quetry.

.My invention will be more fully understood w1th :reference to the annexed drawings, in

I which-- Figure 1 shows a top view of a part of my improved parquetry. Fig. 2 is a cross-section across the lists on the lines a b. Fig. 3 is a cross-'section of the parquetry along the lists on the line c d of Fig. 1. Fig. 4 is a detailed sectional view showing a modification of my improvement.

The fiooring consists of boards I, fixed in the usual manner. Upon this flooring listsH are nailedin equal distances from each other. As shown in Fig. 2,,these lists are tongued at h. Small grooved pieces of wood, w, are then put into the reesses between the lists, the said pieces x having double or more thickness of 3 5 the lists H. The'tongues'h of the lists H fill out only half the space of the groove w' of the small pieces o f wood, x, which are kept down on their places by the ltongues h. The intervals above the lists H and between the small 40 Wood pieces y are provided with tongues y', which catch in the upper half part of the grooves x' of the pieces w. In this manner the small pieces y are also kept down on their places by means of the lists H, although they are situated upon the same.

The lists H run through the whole length of lthe room, and the length of the small piecesx and y may vary, and consequently patterns of figures may be laid by means of the same.

Fi g.3 shows, on a larger scale, how pieces of different lengths, A B C D E F, .may be arrauged along thelist. The same pieces, marked with the same letters, are shown in Fig. 1, from which may be observed how patterns can be made by means of the pieces x o Instead of arrauging between the lists H at first the pieces w, and then upon the lists H vthe pieces y, these pieces 3/ may be abandoned and thepieces x, provided with suitable grooves and tongues, may be made so wide that they touch one to another and over .the lists H, as shown inrFig. 4, without departing from the spirit of my invention.

It is evident that these small pieces ought to be cut from different kinds of wood iu order to form patterns of various colors.

My improved parquetry has the advantage that any shrinking or expanding of the fioor will have no influence to the position of the parquetry, and that Wood of different hardness may be employed without having any influence in regard to the equality of wear and te'ar.

Having thusfully described my inveuton, what I olaim, and desire to secure by Letters Patent of the United States, is-

A parquetry made by means ,of lists H, nailed on the tlooring I in equal distance each from the other, and provided with tongu'es h, that hold down small grooved pieces of Wood, w, arranged between the lists H, the pieces x holding down other' small tongued' pieces, y, arranged between the pieces x and lying upon the lists H, as set forth.

- In testimony whereof I have signed my name to this specification in the presence of two sub- 8 5 I scribing witnesses.
